Below you are given the average monthly streamflow from the Saltzmann Creek watershed in Forest Park. If phosphate (PO43-) concentration in the streamflow was found to average 0.155 mg/L throughout the year, estimate (a) the total volume of water (in L) and (b) the total mass of streamwater-exported PO43- (in kg of PO43-) leaving the watershed in an average year.
